NGK CPR8EA-9 (2306) resistor spark plug for reliable ignition, stable running and long service life. Built with corrosion-resistant plating, strong ceramic insulator and copper core for efficient heat removal.
The NGK CPR8EA-9 spark plug (vendor part number 2306) is a dependable choice when you want consistent starts, smooth throttle response and stable engine performance. With a copper core designed to pull heat away efficiently and a pure alumina silicate ceramic insulator for strength and heat transfer, it’s built for demanding riding and regular maintenance intervals.
Its trivalent metal plating helps resist corrosion and reduces the risk of seizing during removal, while triple seals help prevent leakage for more reliable long-term use. If your bike is hard to start, misfiring, or running inconsistently, replacing a worn plug with the correct NGK specification is one of the fastest and most cost-effective fixes.
